Carbonated hydroxyapatite (CHA)-based nanocomposite powders with different zirconia (ZrO2) contents, up to 8 wt.%, were prepared using high-energy ball mill.Phase composition of the resultant nanocomposites was investigated by X-ray diffraction (XRD) technique.Moreover, the crystal size, lattice strain and dislocation density were calculated.In order to measure shrinkage, physical and mechanical p...
